hey, you know the video "highly planned best buy prank"? i heard the same group or organization or whatever does other pranks and videos. do you know what their channel is called? because i thought they had a youtube channel. so, pretty much i'm just wondering where you got this video because they supposedly did more than one. one with like a train station and everyone freezes at one time and unfreezes like 3 min later? i don't know. anyways, thanks! reply back
